Geothermal means, literally, “earth heat”. The temperature of the earth increases as we drill deeper towards its core. We can use that heat for energy by circulating water through hot subterranean reservoirs…

Running a business in Australia’s energy sector is difficult. Proprietors have to contend with intense competition, rapid technological change, climate change, natural disasters…even complaints about rising…
Hydroelectricity is an established power-generation technology with over 100 years of commercial operation. Hydroelectricity is produced when moving water rotates a turbine shaft; this movement is converted…
Let’s be honest: the relationship between renewable energy and the electricity market is complex. So what does the latest report from Australian energy research firm RepuTex tell us? Well, for a start…
The future of civilisation and much biodiversity hangs to a large degree on whether we can replace fossil fuels – coal, oil and gas – with clean, safe and affordable energy within several decades. The…
A carbon price of under $100 per tonne of carbon dioxide would help to make fossil fuels less economical than renewable energies…
There are two main types of solar energy technology: photovoltaics (PV) and solar thermal. Solar PV is the rooftop solar you see on homes and businesses - it produces electricity from solar energy directly…
Earlier this month, Victorians woke to the news that they had a new premier: Dennis Napthine, member for the South-West Coast District, would take over from Ted Baillieu to lead the state. As climate change…
In a survey last year of 22,812 people across 22 countries (including Australia), the polling organisation GlobeScan found that environmental concerns had fallen worldwide since 2009, and fewer than one…
A recent Bloomberg press release got wide coverage with its claim that wind power is now cheaper than coal. But a new report from the OECD shows that when you cover the full cost to the grid, variable…
Storing electricity to use later is critically important to the energy sector and in reducing carbon emissions. In the US…
In Europe and America, electricity retailers let their customers know whether their electricity is coming from renewable energy or fossil fuels. In Australia, your retailer has no such obligation. The…
In visiting Australia regularly for the last two decades I have never quite understood why greater value is not placed on the nation’s latent solar and nuclear energy assets. Perhaps it is because Australia…
Electricity-intensive investment isn’t coming Australia’s way. We use our many natural resources to underpin our productivity and prosperity and we are extracting increasing amounts of metal from the ground…
The UN has set out its ambition for an international policy on sustainable energy. But is the UN’s lead enough? What will it take to make nations follow? Creating and harnessing incentives to participate…
Solar thermal energy will halve in cost by 2020, the new director of the CSIRO’s Australian Solar Thermal Research Initiative said today. Solar thermal energy uses the concentrated heat of the sun to create…
Climate change no longer attracts the headlines it once did, as the recent conference in Doha showed. Global media attention since its 2009 peak during the Copenhagen summit has fallen off a cliff – according…
Many times in human history governments have tried to write policies based around future technologies and missed identifying the transformational keys. In the 1970s, for example, few if any horizon-scanning…
In November 2001, Doha hosted trade talks over intellectual property and public health. The discussions resulted in the landmark Doha Declaration on the TRIPS Agreement and Public Health. The Doha Declaration…
Energy production must shift from fossil fuels to renewable sources within four decades to avoid the most damaging consequences of climate change, a government report has found. The Climate Commission’s…
